- Optimize SVG assets using SVGO and pass custom configs.
- Optimize scalar assets (png, jpeg, gif, tiff, webp, avif) using Sharp.js with the option to pass custom configs for each extension type.
- Option to process all assets from your
publicdirectory defined in the bundler. - Configure
test,include, andexcludeto filter assets. - Skip processing assets if their optimized size is greater than their original size.
- Log the optimization stats showing the before and after size difference, ratio and total savings (optional)
This plugin is based on the awesome image-minimizer-webpack-plugin for Webpack. I wanted to combine the optimization capabilities of Sharp.js and SVGO in a single package and I couldn't find a plugin for Vite that could accomplish this. I initially thought of adding squoosh and imagemin support as well but dropped the idea since they are no longer maintained.
If you find the plugin useful, consider showing your support by giving a ⭐

You can add it as a dev dependency to any of the package managers (NPM, Yarn, PNPM)
Supports Vite >=3 and Node >=14
npm install vite-plugin-image-optimizer --save-devWarning
sharpandsvgodon't come installed as part of the package. You will have to install them manually and add it as a dev dependency. This is a design decision so you can choose to skip installingsharpif you only want to optimize svg assets usingsvgoand vice versa.npm install sharp --save-devnpm install svgo --save-dev
